sz claims.

'Ihis invention relates to improvements in machines for use in the manufacture of shoes'and is illustrated herein as embodied in an assembling machine' of the type disclosed in United States Letters P ent No. 1,356,510, granted October 26, 1920, on a applicationof Hannah Ashton, executrix of the will of Orrell Ashton; in United States Letters Patent No. 1,443,288, granted January 23, 1923, on an application of William Stewart; and in United States Letters Patent No. 1,634,502, granted July 5, 1927, on my application.

It is to be understood, however, that the invention is not restricted to embodiment in a machine of this particular type, certain features of the invention being of more general application to machines for operating upon shoes. For convenience of description the term shoe is hereinafter employed to indicate shoe parts positioned on a last for the various shoemaking operations whereby such parts are shaped to the last, and said term is to be so construed when the context permits that construction.

In assembling shoe parts on lasts by means of assembling machines now in general use, the machine operator positions loosely on a suitable last an upper, which is usually provided with a counter to which adhesive has been applied, and positions the last with the shoe parts thereon on a work support which is initially disposed forwardly from its operative position for the convenience of the operator in positioning a last thereon. In order to position the shoe and its support in operative relation to the operating instrumentalities ofthe machine, the operator moves the shoe on its support from him until they are arrested by the engagement of the shoe with a gage or stop provided by the machine. In so moving the supported shoe, the shoe parts sometimes become disarranged upon the last by reason of the inability of the operator to hold them in position while moving the work and the work support away from him to position them for the assembling operation.

It is an object of the present invention to provide an assembling machine wherein shoe parts loosely positioned on a supported last may be engaged and held securely on the last before the operator swings the work support into operative position.

With the above object in View a feature of the invention comprises a work support movable to and from operative position in an assembling machine, a heel-embracing band movable with the work support as the latter moves to and from operative position, manually operated means herein illustrated as a treadle provided with connections for drawing the band about the heel portion of an upper on a last on the work support while the support is out of operative position, and means herein illustrated as lasting wipers for working the overlasting margin of an upper over'an insole on the last bottom.

While the upper clamping means above referred to is illustrated in an assembling machine it may be constructed and arranged to engage either end of the shoe and it may be employed generally in machines for operating on end portions of shoes, particularly in machines for shaping end portions of shoes upon lasts. Accordingly, a further feature of the invention comprises an end-embracing band in a machine for operating on end portions of shoes and manually operated means for-first moving the ends of a band widthwise of a shoe in the machine toward each other and for thereafter moving the band bodily lengthwise of the shoe.

The illustrated heel' clamping means is also applicable generally to shoe machines provided with work supports, such as that herein illustrated, for the purpose of securing the shoe in predetermined position heightwise thereof and, accordingly, a still further feature of the invention comprises a work support in a machine for operating on shoes comprising a hollow shaft which is immovable endwise thereof, a spindle yieldingly supported therein, and means carried by the hollow shaft, for example the illustrated heel-embracing band, for engaging a shoe supported on the spindle and thereby holding the shoe and the spindle against upward movement.

Before the upper-clamping means isoperated to clamp the upper against a supported last it is desirable that the shoe be located heightwise of the work support in position for thev operations to be performed thereon. To this end the invention, in accordance with a further feature thereof, provides, in combination with a` depressible work support, means, herein illustrated as a depressor, constructed and arranged to move the support with a shoe mounted thereon down-r wardly to a predetermined limit while the support remains at the limit of its movement from operative position, and means, such as a treadle, for actuating the depressor. The depressor is returned to its inoperative position while the shoe support remains at the limit of its movement from its operative position, such return movement being effected automatically in the illustrated` machine after the connections between the depressor and its treadle have been broken. In`

accordance with another feature of the invention,

the connections from the treadle to the depressor are broken by a further actuation of the treadle after the depressor has reached the limit of its downward movement. Before the depressor is permitted to return to its inoperative position it is desirable that the heel-clamping means engage the heel portion of the shoe in order to hold the shoe and its support from upward movement and, accordingly, another feature of the invention comprises manually actuated means for first actuating the depressor, then actuating said heel-clamping means, and finally releasing the depressor.

In accordance with a further feature of thel invention, the illustrated machine is provided with manually operated means for rst moving the ends of the shoe-embracing band widthwise of a shoe in the machine toward each other and for thereafter moving the band lengthwise of the shoe thereby to shape the shoe upon its last. In accordance with another feature of the invention, the illustrated machine is provided with means operable while the shoe support is out of its operative position for effecting relative movement of the shoe and the band thereby to wipe the band lengthwise of the shoe and heightwise thereof toward the shoe bottom. In the illustrated machine the heightwise wiping is effected by the actuation of the depressor.

Assembling machines now in general use do not shape the heel portions of uppers to their lasts but merely operate to fasten uppers to their lasts. It is an object of the present invention to provide a machine which will not only fasten the heel portions of shoe parts to their lasts but will also shape the shoe parts to their lasts and lay the overlastingmargin at opposite sides of the heel portion of a. supported shoe over an insole on the last bottom. It is to be understood, however, that the features of the invention relating to the shaping of uppers upon their lasts are not limited in their application to machines which also assemble such uppers on their lasts or to machines which operate on the heel portions of shoes.

For laying the overlasting margin of an upper over an insole on the last bottom the illustrated machine, in accordance with a feature of the invention, is provided with a lasting wiper, a carrier therefor constructed and arranged for limited movement in an arcuate path about an axis extending heightwise of the shoe, and means, for example a power-energized spring, for ilrst moving the carrier, together with the wiper, through its arcuate path and to the limit of its r movement in said path and for thereafter moving the wiper in a straight line relatively to its carrier.

In shoes provided with molded counters difilculty is'often encountered in seating the flange of the counter, particularly that portion of the flange in the region of the heel breast line, upon the margin of the insole. It is of the utmost importance that the flange of the counter bel firmly seated against the insole before the heel is attached to the shoe bottom and when, as is often the case, the assembling operation and the subsequent side lasting operation fail to seat the counter flange against the insole, the heel-seatlasting machine is required to bend the counter over the edge face of the insole and press its iiange against the margin of the insole. It requlres a heavy and powerful machine to perform this operation on the counter whereas a much lighter machine could be employed to lay the heel-seat portion of the upper over the shoe bottom and secure it thereto. 'I'he best time to seat the counter flange upon the margin of the insole is during the assembling operation before the adhesive on the counter has set and before the ends of the counter wings have been secured by the side laster. With this in view, it is an object of the present inventionl to position the counter accurately in the heel portion of the shoe and to seat the flange of the counter firmly against the margin of the insole. Accordingly, a feature of the invention contemplates the provision in a machine for assembling and shaping the heel parts of shoes Aupon lasts of means for pressing the lasting wiper above referred to downwardly against the margin of the shoe bottom after its carrier has first moved to the limit of its arcuate movement and the wiper h advanced over the heel-seat portion of the oe bottom. In the illustrated machine downward pressure is imparted to the wiper by means which rst moves the carrier through its arcuate path and then advances the wiper over and upon the'heel-seat portion of the shoe bottom.

'I'he lasting wipers above referred to have associated therewith fastening-inserting means, for example tack driving means, which are arranged to drive tacks through suitable openings in the wipers in order to secure the overlasted marginal materials to the insole while the wipers are in advanced position.

These and other features of the invention will now be described with reference to the accompanying drawings and will be pointed out in the appended claims.

In Fig. 1 of the drawings there is illustrated a machine having the general organization disclosed in the patents heretofore identified, to which reference may be had for a detailed description of parts which are not fully described herein.

The illustrated machine is provided with a. base cr column 30 to which is pivoted at 32 an upstanding carrier member 34 comprising a pair of parallel arms connected by a cross-bar 35 which carries a cross-pin 36 to one end of which there is pivoted the lower end of a rod 38 extending downwardly from a hollow shaft 40 of the worksupportng assembly. The rod 38 is secured in the shaft by a screw 42 and supports at its upper end a. spring 44 extending upwardly through a part of the hollow shaft. Said spring, in turn, supports at its upper end a shaft or spindle 46 the upper end of which is provided with a last pin 48 for supporting a last 50 in inverted position. In order to limit movement of the work supporting assembly away from the machine column 30 and also to determine accurately the initial position of the supported last 50 lengthwise thereof relatively to a last-depressing member 10, a link 5I is provided between the upper end of the hollow shaft 40 and a bracket 238 secured to the machine column, one end of said link being secured to a collar 53 loosely mounted on the hollow shaft and supported upon the upper face of a fixture |56 secured to said shaft, the opposite end of said link extending freely through a hole in the bracket 230 (Fig. 3), movement of the link through said hole being limited by a nut 55 secured to the end portion of the link. The spindle 46 is initially positioned endwise of the shaft 40 by a collar 52 loosely mounted on the shaft near its upper end and supported by a finger 54 (Fig. 11) secured to the back of the fixture |56 on the hollow shaft by a screw 51 which also serves to secure the fixture to the shaft, the lower end of the nger 54 being bent inwardly toward the shaft for engagement within a peripheral groove 56 provided in the collar. The bottom edge of the collar 52 extends helically about the hollow shaft 40, and positioned at,intervals around the bottom of the collar are notches 58 (Fig. 16) which receive alternatively a screw 66 extending radially from the spindle 46 through a. slot 62 provided in the hollow shaft 40 and extending endwise thereof, said slot being long enough to permit adjustive movement of the spindle 46 within the shaft 40 within the range of adjustmentaiforded by the notches 58 in the collar 52 and also to permit movement of the spindle by the depressor arm 10 as hereinafter described. 'I'he toe end of the supported last and upper rest upon a toe support 64 mounted in a slide 66 and adjustable in said slide heightwise of the supported last, said slide, in turn, being adjustable lengthwise of the last on a supporting arm 68 which is secured to the spindle 46. 'Ihe illustrated shoe support is substantially the same as the toe support illustrated in Patent No. 1,634,502, above referred to. It will be seen that the screw 60 which engages the notches in the collar 52 also holds the spindle from turning in the hollow shaft and holds the arm 68 in the plane of movement of the hollow shaft 40.

'Ihe collar 52 is adjusted in accordance with the average height of lasts of the class of shoes to be operated upon in order to position the heelseat portion of the last bottom slightly above its operative position heightwise of the work support t thus to permit a slight depression of the supported last and the spindle 46 to locate the heel-seat portion of the last in proper position heightwise of the work support for engagement by the operating instrumentalities after the work support has been swung into its operative position. In the illustrated machine such depression of the last and its supporting spindle is effected, while the work support is at the limit of its movement from its operative position, by a manually-actuated depressor which, as herein illustrated, consists of a horizontally-disposed arm 10 (Fig. 3) pivoted to the machine frame and extending forwardly therefrom, said arm having pivoted to its free end a short arm 12 extending downwardly from the arm 10 and having a presser foot 14 pivoted to its lower end. The arm 10 positions the presser foot 14 above the heel-seat-portion of the supported last and substantially centrally of the last widthwise thereof. In operating upon uppers provided with molded counters it is desirable thatI the presser foot 14, during its downward movement, engage the flange of the counter, for example the ange 16 of a counter illustrated in Fig. 6, and press said flange downwardly against an insole 18 on the last bottom, thereby positioning the counter heightwise of the supported last. In order to adjust the presser foot lengthwise of the supportedlast for different sizes of lasts, thereby to insure .the engagement of the presser foot 14 with the flange of the counter, an adjusting screw is swiveled in the short arm 12 extending downwardly from the arm 18 and threaded in a tapped hole in a block 82 pivoted to the arm 10 and depending therefrom. A spring 84 positioned on the screw 80 between the block 82 and a washer 86 adjacent to the back of the short arm 12 yieldingly maintains the adjustment of the presser foot while permitting the arm 12 to swing slightly in a clockwise direction as seen in Fig. 6 during the downward movement of the arm 10 after the presser foot has come into engagement with the counter, thus obviating any movement of the presser foot lengthwise of the last after the presser foot has engagedthe counter. The depressor assembly is normally held above the bottom of the supported shoe by a spring 88 (Fig. 2), the upper end of which is anchored to the machine frame and the lower end of which engages the forward end of an arm 90 pivoted to the machine frame coaxially with the depressor arm 10 and"-secured in a position ofalinement with the arm v'|01bya cross pin 92 (Fig. 12) the opposite ends of which havqnuts threaded thereto while the enlarged central'portion spaces the arms 10 and 90 from each other. The upward movement of the depressor assembly is limited by the engagement of the cross pin 92 with an abutment screw in a bracket 93 on the machine frame. For manually operating the depressor arm 10 a treadle 94 (Fig. 1) is pivoted at 91 to the forward end of the cross-pin 36 and is connected by a link 96 to the forward end of a lever 98 which is pivoted to the outer surface of the upper end portion of one of the' arms of the carrier member 34. The rear portion of the lever 93 has formed therein a flange |00 which provides a cam face which engages a cam follower or roll |02 pivoted to the end of the upwardly extending arm of a bell-crank lever |04 which, in turn, is pivoted to a rearward extension of that arm of the carrier 34 to which the lever 98 is pivoted. The roll |02 is held in engagement with the cam by a spring |22, one end of which engages the upwardly extending arm of the bell-crank,

lever land the other end of which engages an upward extension |24 of the lever 98. 'I'he horizontal arm of the bell-crank lever |04 is provided with a detent |06 constructed and arranged for engagement with a latch face |08 provided in a link ||0 which is pivoted at its upper end to the forward end of the arm 90. The lower end of the link 0 is yieldingly urged rearwardly thereof to position it relatively to the detent |06 by a spring 2, the rearward end of which is anchored to an arm ||4 pivoted to a cross-shaft journaled in the machine frame, the forward end of the spring engaging a cross-pin ||6 in the lower end of the link. The movement of the lower end of the link ||0 by the spring ||2 is limited by the engagement of the cross-pin 6 at the rearward extremity of a slot ||8 in the forward end of the arm ||4. In ordery to maintain an accurate orientation of the lower end of the link |0 relatively to the detent |06, the link is provided at opposite sides thereof with flat faces which slide between flat surfaces of ears formed in a block (Fig. 7) secured to a cross-pin ||3 in a forward extension 238 of the bracket 230. The extent of downward movement of the depressor arm 'I0 may be adjusted by turning a turn-buckle |20 (Fig. 1) connecting the upper and lower portions of the link I0.

In order to hold the spindle 46 and the last and upper supported thereon from downward movement by the tack driving arm 3|8 which tacks the overlasting margin of the heel portions of the upper materials to the insole, means is provided for locking 4the spindle 46 against downward movement, the illustrated locking means comprising a ring |26 (Fig. 4) loosely encircling the hollow shaft 40 and pivotally mounted between the upper ends of the arms of the carrier member 34, said ring having a ratchet member |28 secured in a boss |29 extendinglforwardly therefrom, the upwardly extending teeth in said member being arranged for engagement with downwardly extending ratchet teeth formed in a collar |30 slidably mounted on the hollow shaft 40 and secured by a screw |32 (Fig. 5) to the lower end of the spindle 46. In order that the screw |32 shall not prevent the required relative movement of the hollow shaft 40 and the spindle 46, the hollow shaft is provided with a longitudinal slot |34 for the reception of the screw |32, said screw traveling lengthwise of the slot during such relative movement. The ratchet members are held disengaged from each other while the supported shoe is out of operative position by a ated to move the carrier member 34 toward the machine column after said member and the work support mounted thereon have been manually swung rearwardly toward the machine column.

In order to hold the supported last 50 against upward movement by the spring 44 in the hollow shaft 40 after the last-depressing mechanism has located the last in operative position heightwise of the Work support, a heel-embracing band |42 (Fig. 1) is brought into engagement with the heel end of the upper on the last by mechanism actuated by the treadle 94. After the band 42 has engaged the upper, continued depression of the treadle 94 imparts forward movement to a link |44 the forward end of which is pivoted to the upward extension |24 of the lever 98 and the rear end of which is slidably mounted in an opening in the link ||0 and has secured thereto a. nut |45 which engages the rear face of the link. The forward movement of the link |44 disengages the link ||0 from the detent |06, thereby permitting the depressor arm 10 to be raised by the spring 88, thus disengaging the presser foot 14 from the shoe bottom and pei'- mitting movement of the shoe supporting assembly to its operative position.

Referring now to the heel band |42 and its supporting and operating mechanism, said band, as illustrated in Fig. 16, is supported by its opposite ends on a pair of upstanding arms |46. Referring to Fig. 12, the heads |50 of the arms |46 are provided with arcuate T-ways within which are slidably mounted suitably constructed blocks |48, said blocks being provided with anges |49 which overlie the heads |50 of the arms |46. Secured to said flanges by screws |5| are angle plates |53, the downwardly extending portions of which are riveted to the end portions of the heel band 42. Each of the blocks |42 swivels about an axis which intersects the upper-engaging surface of the band. The arms |46 are pivotally mounted on blocks |52 (Fig. 16) which, in turn, are journaled on trunnions |54 extending in opposite directions from the fixture |56 secured to the upper end of the hollow shaft 40. In order to permit a limited swinging movement of the blocks |52 on their trunnions, the pins |58 which pass through extensions |60 and |62 of the arms |46 and connect them to the trunnion blocks |52 extend through holes |64 provided'in the trunnion blocks, which holes are of substantially larger diameter than said pins. The extensions |60 and |62 form yokes in the arms |46 which embrace the trunnion blocks and position the arms |46 thereon. The heel band 42 is yieldingly held in inoperative or retracted position by springs |66 connecting the downward extensions |62 of the arms |46 to the hollow shaft 40 (Fig. 1). Upon depressing the treadle 94 the arms |46 upon which the heel band is supported are swung toward each other simultaneously with the downward movement of the depressor arm 10, the movement of said arms being effected through links |68 the upper ends of which are mounted in arms |10 formed integrally lwith the downward extensions |60 of the arms |46 and arranged to extend toward each other. The lower ends of the links |68 have ball and socket connections with a cross-bar |12 `(Fig. 21) secured to a plunger |14 slidably mounted in a cylindrical boss |16 in the treadle 94, a compression spring |18 being mounted on the shank |80 of the plunger |14, one end of said spring being seated against the head of the plunger and the other end of said spring being seated at the upper extremity of the bore in the boss |16 through which the head of the plunger slides. The spring |18 is compressed by the treadle 94 during the latter part of its downward movement, thereby pressing the heel band against the upper on the supported last. As seen in Fig. 16, the links |68 at their points of engagement with the arms |10 are farther from the .center lines of the pins |58 than they are from 'the common center line of the trunnions |54, while the springs |66 which hold the heel band in retracted position are spaced at uniform distances from both center lines. Thus it will be seen that the force applied by the springs |66 to the arms 46 tending to swing said arms lengthwise of a supported shoe is equivalent to the force applied by said springs to said arms tending to swing said arms widthwise of a supported shoe, while, on the other hand, the force applied by the links |68 to the arms |46 tending to swing said arms widthwise of a supported shoe is substantially greater than the force applied by the links |68 to the arms |46 tending to swing said arms lengthwise of a supported shoe, the leverage exerted by the links |68 to swing the arms |46 widthwise of a supported shoe being preferably double the leverage exerted by the links |68 on said arms to swing the arms lengthwise of a supported shoe. Consequently, the depression of the treadle 94 operates first to move the arms |46 widthwise of a supported shoe and no movement of the arms lengthwise of a supported shoe takes place until after the arms have exerted a substantial pressure against the sides of the shoe. The` swinging movement of the arms |46 about the trunnions |54 imparts to the heel band |42 a bodily movement, or a movement of translation, forwardly of the supported shoe. Since the last and the shoe parts thereon are being moved downwardly by the presser foot 14 during said bodily movement of the heel band, the band moves relatively to the upper on the last simultaneously forwardly of the last and toward the last bottom, the two extremities of said movement being indicated by theA two positions of the heel band illustrated in Fig. 17. The band is held in heel-embracing position during the movement of the work support to operative position and during the operations on the shoe by a latch dog |82 (Fig. 1) pivoted to the rearward end of the treadle 94 and arranged to extend upwardly therefrom for engagement with a latch face formed in the rearward end of the cross-pin 36 in the carrier member 34, said latch dog being yieldingly held against the rear end of said cross-pinby a spring |84 connecting the latch dog to the central portion of the treadle.

In Figs. 18, 19 and 2O there is illustrated an alternative means for clamping the upper against the supported last comprising a pair of gripping arms or clamps |86 pivotally mounted between the arms of an H-shaped fixture or collar |81 secured to the spindle 46 betweenthe arm 68 and the last pin 48 and disposed transversely of said arm 68. The gripping arms |86 are provided at their upper ends with pads |88 constructed and arranged to engage the top margin of an upper on a supported last and normally held out of upper-engaging position by a spring |89 (Fig. 19) connecting downward extensions of the arms |86. For operating the gripping arms |86 to bringthe pads into engagement with the upper. the arms |46 which carry the heel band |42 also carry screws |90, the ends of which are arranged to abut the gripping arms |86, said arms being provided with extensions |92 to insure continued engagement of the screws |90 with the arms during the movement of the heel-band-supporting arms |46 forwardly of a supported shoe. Referring now to Fig. 20 illustrating one of the screws |90 and its supporting assembly, said screw is mounted in a collar |94 slidably mounted in a boss 202 in the arm |46, said collar being provided with a central hole threaded for part of its length for the reception of the screw |90. For securing the screw |90 relatively to the collar |94 the screw carries a lock nut 204 arranged for engagement with the outer extremity of the collar. In order to limit movement of the collar |94 in the direction of the arm |86 the lock nut 204 has formed therein a flange 206 arranged to engage the outer end face of the boss 202. The flange 206 is yieldingly held in engagement with the boss 202 by a spring 208, the major portion of which is arranged within a. bore 2I0 extending outwardly of the heel-band-supporting arm |46 from its inner face. The inner end of the spring 208 is seated in a socket in a flange |96 on the collar |94, said socket being held in alinement with the bore 2|0 by a, dowel pin |98 secured to the ange |96 and slidably mounted in a hole 200 in the boss 202. 'Ihe spring 208 urges the flange |96 of the collar |94 away from the inner face of the heel-band-supporting arm |46 and maintains a determinate spaced relation between the opposite faces of the flange and the arm, which space is initially occupied by a spacer herein illustrated as a swinging L-shaped member 2|2 (Fig. 18) pivoted at the apex of the angle defined by its diverging arms to the inner surface of the heel-band-supporting arm |46 below the boss 202, the end of the upstanding arm of said L- shaped member being provided with a curvedA finger 2|4 constructedand arranged for engagement with the collar |94 adjacent to its ange |96. As illustrated in Fig. 20, the space maintained by the spring 208 between the flange |96 and the arm |46 is suiilcient to permit the spacer arm 2 I2 to move freely into said space. For disengaging the spacer arms from the collar |94 an auxiliary treadle 2|6 (Fig. 21) is pivoted to the cross-pin 36 coaxially with the treadle 94 and provided with a lug 2|8 in which sockets are provided for the ball ends of a pair of links 220 the upper ends of which have ball and socket connections with the ends of the horizontal arms of the spacer members 2|2. The spacer members are normally held in engagement with the collar |94 by a treadle spring 222 connecting the auxiliary treadle 2|6 to the arm 34. It will be seen that the screws |90 carried by the heel-bandsupporting arms |46 not only serve to impart to the upper-gripping members |86 the inward motion imparted to the arms |46 by the treadle 94 but also serve to limit the movement of the heel band widthwise of a supported shoe. The screws |90 are preferably so adjusted that depression of the treadle 94 brings the upper-gripping members |86 rmly into engagement with the top margin of the upper and presses the ends of the heel band lightly against the opposite sides of the upper. It will be seen, however, that the engagement of the screws |88 with the arms |86 does not limit the bodily movement of the heel band forwardly of a supported last, the ends of said screws being free to slide Widthwise of the-arms |86 and their extensions |82 as the arms |46 swing forwardly of the supported shoe.

Thus it will be seen that after the treadle 84 has been fully depressed and latched in depressed position the pads |88 are pressed firmly against the top margin of the upper while the curved portion of the heel band is pressed firmly against the back of the heel portion of the upper and the ends of the heel band are urged with a relatively light pressure against the opposite sides of the heel end of the upper. 'I'he iight pressure of the ends of the heel band against the sides of the upper, if the screws |88 are properly adjusted, affords an opportunity for the operator to pull up the lining and the wings of the counter. at opposite sides of the heel portion of the shoe and said band holds the counter and lining in the positions in which they are thus located. The auxiliary treadle 2|6 may then be depressed to disengage the spacer members 2|2 from the collar |84, thereby permitting further movement of the arms |46 toward each other by the compression spring |18 in the treadle 84, thus clamping the ends of the heel band firmly against the opposite sides of the heel end of the upper. When the auxiliary treadle is released the treadle spring 222 swings the spacer members 2|2 upwardly into engagement with the flanges |86 of the collar |84 and when the upper-gripping members are released, as hereinafter described, the compression springs 2|8 return the collars |84 to their .initial positions, whereupon the spacer members 2|2 are returned by the treadle spring 222 to their initial positions, as illustrated in Figs. 118 and 20.

Referring now to the mechanism for working the overlasting margin of the heel portion of a supported upper over an insole on the bottom of a supported last (see Fig. 7), two pairs of wiper and tacker units are supported respectively upon two carriers or rods 224 which are positioned at opposite sides of the bracket 238 and clamped in predetermined position both rotatively thereof and endwise thereof in horizontal holes provided in swivel blocks 226 journaled on vertical shafts 228 mounted in suitable bearings in the bracket 238, said swivel blocks being supported at the upper extremities of said bracket. In the illustrated machine the construction of the pair of Wiper and tacker units and the parts associated therewith operating on one side of the shoe is substantially the same as the construction of the corresponding pair of units and their operating parts for operating on the opposite side of the supported shoe. A description of one pair of units and the parts associated therewith will suilioe for both assemblies and one assembly will now be described in detail. Secured to the upper end of the shaft 228 on which one of the swivel blocks 226 is mounted is an actuator arm 232 the forward end of which is positioned opposite the outer end of the rearward wiper and tacker unit. When the machine is at rest the actuator is held at the limit of its outward or retractive movement by the cam hook |48 which is then at the linut of its upward movement, as illustrated in Figs. 1 and 7, and is supporting on its upper surface a roll 234 pivoted to the end of the horizontal arm of a bell-crank lever 236 pivotally mounted in the forward extension 238 of the bracket 238, the end of the vertical arm of said lever engaging a pair of arms 248 secured to the shaft 228, respectively. Thus the cam hook |48 holds the actuator arm 232 in retracted position. Opposing said cam hook is a torsion spring 242 surrounding the shaft 228, one end of said spring being mounted in a collar 244 on said shaft and the other end of said spring being secured tothe bracket 238. As the actuator arm 232 is retracted by the cam hook |48 its surface 246 engages a lug 248 extending upwardly from the swivel block 226, thereby swinging the wiper and tacker assembly out of shoe-engaging position. In the illustrated machine thev rod 224 which carries the wiper and tacker assembly is clamped to the swivel block 226 by means of a U-shaped clamping member or key 268 which is positioned in a groove in the swivel block 226 extending lengthwise of the hole provided therein, the outturned end portions of said clamping key engaging opposite faces of the swivel block and preventing movement of the key lengthwise thereof relatively to said block. A groove is provided in the wiper-carrying rod 224 for the reception of said clamping key and a clamping screw 252 is threaded in a tapped hole in the swivel block 226 which is arranged to bring the end of said screw into engagement with the clamping key. The groove which is provided in the wiper-carrying rod 224 for the reception of the key 258 is of sufllcient length to permit adjustive movement of the rod endwise thereof in the swivel block 226 in order to permit adjustment of the wiper and tacker units to adapt them to operate on shoes of all sizes. Referring now to Fig. 8, there is mounted on the rod 224 a swivel block 254 having a T-way in its upper portion extending transversely of the rod 224, within which T-Way a slide 266 is mounted for limited movement toward and from the supported shoe. The movement of the swivel block 264, and the parts supported thereon, toward the supported shoe is limited by an abutment screw 268 having threaded engagement in a boss 262 extending downwardly from the swivel block 254, the end of said abutment screw being arranged to engage the head |58 of one of the heel-band-carrying arms |46. The abutment screw 268 is yieldingly held in adjusted position by a springpressed ball 263 (Fig. 14) positioned in a socket in the swivel block 264 for engagement in a longitudinal groove 265 in the screw. The swivel block 264 is freely mounted upon the rod 224 but is held against endwise movement thereon between a pin 264 (Fig. i3) extending diametrically through said rod and a torsion spring 266 surrounding said rod and having one of its ends secured by a collar 268 fastened to said rod while the other end of said spring is extended through an ear 218` on the swivel block 254. The torsion spring 266 also operates to urge the swivel block 254 and the parts mounted thereon in a clockwise direction, as seen in Fig. 8, such clockwise movement being limited by the engagement of a stop screw 212 (Fig. 13) mounted in the swivel block with the pin 264 in the rod 224, said swivel block being provided with notches 214 for the reception of said pin in order to permit said pin to be positioned in opposition to the stop screw 212. The adjustment of the stop screw 212 determines the initial position of the swivel block 264 and the parts thereon, thereby determining the initial elevation of a lasting wiper 216 secured to the under surface of the slide 256. Preferablythe stop screw is so adjusted that the wiper 216 is initially located slightly below the level of the heel-seat portion of a supported shoe, thereby insuring a substantial pressure of the wiper against the overlasting margin 218 (Fig. 8) by the torsion spring 266 as the wiper moves inwardly over the shoe bottom. The slide 256 is yieldingly held at the limit of its movement away from the supported shoe by a compression spring 289 (Fig. 14) contained within a hole extending through the slide lengthwise thereof, one end of said spring abutting a headed screw 282 and the other end of said spring abutting a stud 284 extending upwardly from the base of the T-way in the swivel block 254, the slide 256 being slotted, as shown in Fig. 13, to permit movement thereof relatively to said stud. The head of the screw 282 is engaged by the actuator arm 232 as said arm advances to swing the wiper and tacker assembly toward the supported shoe, the spring 288 operating to maintain the slide 256 at the limit of its retractive movement until lthe abutment screw 268 has engaged the head |58 of the heelband-carrying arm |46, the limit of the retractive movement of the slide being determined by the engagement of the rear end face of the wiper 216 with the adjacent face of the swivel block 254. Further advancement of the actuator arm 232 after the abutment screw 268 has engaged the arm |46 advances the slide 256 against the resistance of the spring 288 thereby moving the wiper 216 inwardly over the everlasting margin 218 of the supported shoe (Fig. 8) such advancing movement of the wiper being limited by the engagement of the head of the screw 282 with the face 286 of the swivel block 254, the head of said screw being made large enough to extend beyond the end face of the slide 256 for engagement with said face 286 of the swivel block. If the overlasting marginal materials 218 include the flange of a molded counter, said ange, in some cases, will tend to hold the margin of the upper together with the lasting wiper 216 slightly elevated, as illustrated in Fig. 10, as the wiper advances over the shoe bottom. In order to overcome this condition and to bring the overlasting marginal materials 218 firmly against the insole 292, as illustrated in Fig. 9, the force of the torsion spring 242 on the shaft 228 (Fig. '7) augments the force of the torsion spring 266 after the wiper has come to the limit of its movement over the shoe bottom, ther'eby insuring a sufcient downward pressure of the wiper 216 against the overlasting margin 218 to position the marginal materials firmly against the margin of the insole before the tack 294 is driven. Extending upwardly from the outer portion of the slide 256 is an arm 288 to which there is clamped a tacker unit comprising a plate 298, a portion of which extends upwardly in the form of a hollow shaft 29|, said shaft having s'lidably mounted therein a rod 293 which carries a tack driving pin 295. Mounted in grooves in opposite sides of the bottom margin of the plate 298 are arms 291 which` provide the opposite walls of a tack pocket 299 (Fig. 15), said arms being held in position by a spring 38|. In order to hold the driving pin 295 in retracted position, as illustrated in Fig. 15, a spring 383 is coiled about the hollow shaft 29| between a washer 385 at the base of said shaft and a headed cap 381 secured to the upper end of the rod 293, upward movement of the tack driver being limited by the engagement of a cross-pin 389 in the rod 293 at the upper extremities of grooves 3|| provided in the hollow shaft 29|. Secured to the forward face of the tacker member 298 illustrated in Fig. 15 is an upstanding plate 2 98 the bottom margin of which is bent rearwardly into a horizontal position and extended to the right, as seen in Fig. 15, to form a lasting wiper 388. For lasting a portion of the overlasting margin 218 forwardly of that portion of said margin which is operated upon by the wiper 216 the wiper and tacker unit illustrated in Fig. 15 is mounted on studs 388 and 3|8 (Figs. 12 and 14) extending forwardly of the shoe from the arm 288 which extends upwardly from the slide 256, the tacker member 296 of Fig. 15 being provided with holes 384 and 386 which receive said studs. When the wiper and tacker unit of Fig. 15 is mounted on the studs 388 .and 3|8 the lasting wiper 388 thereof is arranged substantially in alinement transversely thereof with the lasting wiper 216. It will be seen that the lasting wiper 388 and the tacker 296 associated therewith are adjustable lengthwise of the shoe within the limits prescribed by the length of the studs 388 and 3| 8. The rear portions of the studs 388 and 3| 8 extend through suitable holes in the arm 268 (Fig. 14) and through cor,- responding holes in an extension 3 I2 of the tacker unit 298, the ends of said studs projecting from said extension 3|2 being threaded for the reception of clamping nuts which secure the tacker unit 298 to the arm 288 and secure the studs 388 and 3|8 in position for supporting the tacker member 296. In order to permit the tacker member 296 to be clamped in adjusted position endwise of the studs 388 and 3|8 the extension 382 is provided with slots 3|4. The split clamp thus provided is closed upon the studs 388 and 3|8 by a thumb screw 3|6. 'Ihe wiper and tacker unit of Fig. 15 being held against movement relatively to the tacker unit 298 upon which it is supported, it will be seen that the actuator 232 imparts to the wiper 388 substantially the same movements widthwise and heightwise of the shoe which it imparts to the wiper 216.

Referring now to Fig. 2, the tack drivers which tack the everlasting margin of the heel portion of the upper to the insole are actuated by a tackdriving arm 3|8 which is operated by a torsion spring 328 in timed relation to the actuation of the wipers 216 and 388. 'I'he tack-driving arm 3|8 drives two tacks at each side of the shoe. said tacks being driven through suitable openings in the wipers, and it also drives a tack through the rear margin of the heel seat at the center of said margin widthwise of the shoe. For driving the side tacks the head 322 of the tack driver 324 which drives the central heel-seat tack is extended forwardly, as illustrated in Fig. 2, and has secured therein a threaded stud 326 extending upwardly from a horizontal plate 328 which is constructed and arranged to engage the heads of the four side tackers substantially simultaneously.

While the operation of various parts of the machine has been described heretofore, the following description of the operation of the machine may serve to promote a better understanding of the invention. Before operating on a given run of shoes the toe post 64 (Fig. 1) is adjusted in accordance with the contour of the bottoms of said shoes in order to cause the heel-seat portion of the bottom of a supported shoe to be so positioned that all of the five tacks to be driven into the heel-seat portion of the shoe bottom will be driven home and clenched. 'I'he operator then places on the work-supporting spindle 46 a last with an insole attached to its sole face, said last having arranged thereon an upper provided with a. molded counter to which adhesive has been applied. After positioning the last and s upper on the work support the operator depresses the treadle 94 while the work support remains in its forward or inoperative position, as seen in Fig. 1. The depression of the treadle turns the lever 96 in a clockwise direction from its position in Fig. 3 to its position in Fig. 1, thereby imparting downward movement to the depressor arm 10, bringing the presser foot 14 into engagement with the flange of the counter (Fig. 6), positioning the counter in proper relation to the heel portion of the last 50 heightwise thereof and, after seating the flange of the counter against the margin of the insole 16, imparting downward movement to the supported last and upper and the work-supporting spindle 46, thereby bringing the heel-seat portion of the last bottom into a position heightwise of the'work support -predetermined by the adjustment of the turn buckle |20 on the link ||0. Simultaneously with the downward movement of the depressor arm the treadle 94 swings the heel-band-supporting arms |46 toward each other to bring the end portions of the heel band |42 into engagement with the opposite sides of the heel portion of the upper, said end portions of the band coming into engagement with the upper as the presser foot 14 comes into engagement with the flange of the counter. As the presser foot moves the last and upper downwardly as heretofore described the heel-band-supporting arms |46 swing forwardly of the supported last, wiping the band forwardly of the upper and bringing the curved portions of the band against the back of the heel portion of the upper, thereby drawing the upper materials firmly against the back of the last and working the sides oi' the heel portion of the upper materials forwardly of the last and also upwardly thereof by reason of the depression of the last during the forward movement of the arms |46 (Fig. 17). 'I'he combined forward and upward movement of the heel band |42 thus eiected insures a firm engagement of the top margin of the upper at the back of the heel with the last and also insures positioning the margins of the counter wings well above the bottom of the insole in the most desirable position for its permanent attachment to the shoe by the subsequent operations of the machine. Continued depression of the treadle 94 after the heel band has come to the limit of its movement forwardly of the supported last compresses the spring |60 carried by the treadle, the pressure of said spring being delivered to the heel band in order to hold the band in clamping engagement with the upper during the subsequent operations of the machine. While the spring |16 is being compressed the presser foot 14 remains stationary since the cam roll |02 on the bell- 'crank lever |04 which operates the depressor arm 101s riding on a dwell in the cam face |06 in said lever 96 during this portion of the depression of the treadle 94. As the treadle nears the limit of its depression it operates through the link |44 (Fig. 6) to disengage the link ||0 from the detent |06, whereupon the depressor assembly is returned to its initial position. As the treadle comes to the limit of its depression the latch dog |82 carried thereby engages the cross-pin 36 and locks the treadle against upward movement. The operator then swings the work support rearwardly toward the machine column, thereby operating a one-revolution clutch to connect a cam shaft 330 to a continuously rotating pulley, thus starting the power cycle of the machine. At the beginning of the power cycle the cam hook |40 swings downwardly, engaging a roll carried by the re ward vextension of the arm 34, thereby imparting further rearward movement to the work support and seating the heel end of the uppei` firmly against a heel stop 332 (Fig. 12). The downward movement of the cam hook 40 also serves to release the torsion springs 242 (Fig. 7), whereupon said springs move the actuator arms 232 toward each other. The movement of the actuator arms swings the carrier rods 224 and the parts mounted thereon toward each other until the movement of said carriers is arrested by the engagement of the stop screws 260 (Fig. 8) with the heads of the heel-bandcarrying arms |46. Further movement of the actuator arms 232 toward each other by the force of springs 242 moves the wiper-carrying slides 256 relatively to the carriers 224 to advance the wipers in straight lines over the margin of the shoe bottom. Still further ad vancement of the actuator arms 232 after the wiper-carrying slides 256 have come to the limit of their movement relatively to the swivel blocks 254 swings the wiper and tacker assemblies about their carrier rods 224, thereby imparting tothe wipers a downward movement to bring the overlasting margin 216 down firmly onto the insole 292 before the tacks are driven, and thereby insuring a proper positioning of the flange of the counter and the other overlasted upper materials upon the heel-seat portion of the insole. While the wipers remain in advanced position the tack-driving arm 3|6 operates to drivethe five tacks illustrated in Fig. 12 through the overlasted marginal materiais 216 and through the margin of the insole 292 against which the tacks are clenched by the heel plate on the last. If desired, the tack-driver 334 (Fig. 2) may be operated to drive a temporary tack through the back of the upper and into the end of the last in order to insure the retention of the line of the back seam during the subsequent operations on the shoe. During the remainder of the cycle of operations after the tacks have been driven the cam hook 40 is elevated, thereby swinging the bell-crank lever in a clockwise direction, as seen in Fig. 7, thus swinging the arms 240 on the vertical shafts 226 forwardly, such movement of the shafts 226 swinging the actuator arms 232 away from each other and bringing the surfaces 246 of said arms into engagement with the lugs 246 on the swivel blocks 226 and thereby returning the wiper and tacker units to their initial positions. 'I'he swinging of the arms 240 also energizes or winds up thev springs 242 for the next operation of the machine. As the work support approaches the limit of its movement from operative position, the latch dog |62 which holds the treadle 94 at the limit of its depression is engaged by a hook 336 pivoted to the machine column 30 which hook engages and holds the upper extremity of the latch dog |62, causing the latch dog to swing about its pivotal connection with the rear end of the treadle 94 during continued movement of the work support from operative position and thereby disengaging the latch dog from the cross-pin 36 and permitting the return of the heel band |42 to its initial position by the springs |66. In order to permit the latch dog |82 to engage the under surface of the forward end of the hook 336 and to lift the hook slightly as the work support swings toward its operative position the elevation of the forward end of said hook is accurately determined by the engagement of a stop screw 342 in an arm 344 extending downwardly from said hook with the front of the machine column.

'I'he initial position of the heel band lengthwise of the supported shoe is determined by the engagement of stop screws 338 (Fig. 8) mounted in arms 340 formed in the blocks |52 with suitable surfaces provided in the xture, |56 secured to the hollow shaft 40. The initial position of the heel-band-carrying arms |46 widthwlse of the supported shoe is determined by the engagement of extensions 352 of the respective arms with the arms 34|).

When the machine is provided with theupperclamping 'mechanism illustrated in Fig. 18 the last-depressing arm 10 is so adjusted heightwise of the supported last that the downward movement of the last and its supporting spindle 46 is completed before the gripping arms |86 swing in against the top margin of the upper. Thus it will be seen that the forward and upward wiping action of the band |42 illustrated in Fig. 17 and heretofore described is not obtained when the alternative construction of Fig. 18 is employed. 'Ihis construction is Well adapted for use in operating on uppers of the conventional type such, for example, as the upper 346 illustrated in Fig. 1 since in this type of upper it is often desirable to operate on the heel portion of the lining with hand pincers in order to draw the lining into smooth condition upon the last and to eliminate any wrinkles that may have occurred when the counter was positioned in the heel end of the upper, and this operation may conveniently be performed while the pads |88 are clamped against the top margin of the upper and While the end portions of the heel band |42 are pressed lightly against the upper to hold the lining in the position in which it is located by the hand pincers.

The upper-clamping mechanism illustrated in Fig. 16 is well adapted to operate on shoes in which the lining at the heel portion of the shoe is stitched to the upper to form a counter pocket since such linings are accurately positioned relatively to the upper when the seam creating the counter pocket is formed and consequently no special attention thereto is required. The construction illustrated in Fig. 16 is particularly adapted to operate on the quarters of uppers such as that illustrated in Figs. 3, 6, and 17 in which the quarter 348 is not attached to the vamp 350 but is assembled on the last and shaped thereto after the vamp has been assembled and shaped to the forepart of the last. It is obvious that `no tensioning of the quarter 348 lengthwise of the last is effected in the pulling-over operation as performed on such shoes since the quarter has not been assembled on the last when that operationv takes place and consequently the tensioning of the quarter forwardly of the last which, in operating on shoes of the conventional type, is effected in the pulling-over operation must be effected in a subsequent operation in the manufacture of shoes provided with the type of upper illustrated in Fig. 17. 'I'he mechanism illustrated in Fig. 16 is well adapted to engage the quarter 348 and work it forwardly of the last 50 since the heelembracing band, as hereinbefore described, firmly engages the opposite sides of the heel portion of the upper before the arms |46 swing forwardly of the supported last to bring the heel band into the position illustrated by full lines in Fig. 17. During such forward movement of the arms |46 the heel band is therefore'in frictional engagement with the upper and operates to work the upper forwardly of the last and simultaneously heightwise thereof toward the last bottom. thereby working the heel part of the upper forwardly of the last and shaping the heel part to the heel portion of the last. This operation of the heel band is particularly effective to shape the portion of the quarter 348 in the region of the back seam to the heightwise curvature of the heel end of the last.

While it is considered preferable to vemploy the alternative heel-engaging devices as above described, it is to be understood that neither the heel-embracing band of Fig. 16 nor the heel-engaging devices of Fig. v18 are limited to use in the manufacture of certain kinds of shoes, but, on the contrary, both constructions may be employed in the manufacture of any and all sorts of shoes in which the uppers are shaped upon lasts and their margins are lasted over insoles on the last bottom.
